I set up a pc at my mom's house with some security cameras attached, and I had trouble with the power going off occasionally. In the BIOS there was a setting to tell the computer to boot whenever the external power came on, but it was poorly named; something like 'Power Off Options.' There were three options, boot, don't boot, and boot if it was running when external power went off. It works, mostly, but it does not have an orderly shutdown when the power goes off. I think that would improve things.<div>

externally I would guess and that's not an orderly shutdown besides with<br>
the UPS in line, I don't really have a way to sense when the mains<br>
actually come back.<br>
<br>
I've thought about putting a small controller, like a Arduino, somewhere<br>
with a relay to momentarily key the switch leads in the computer when I<br>
sense all is back to normal, but I'm thinking there might be a better way.<br>
<br>
Any ideas?<br>
